The company owns and operates a portfolio of brands within the firearms industry. Over the past 6 years, the company has grown at a rate that could secure a position in the upper half of the Inc. 500 list of fastest growing companies in America.

We utilize state of the art 5-axis CNC machines to mill all our .308 and AR-15 80 percent lower receivers to incredibly precise tolerances using premium billet aluminum. We also offer our patented AR-15 and .308 Easy Jigs which is the first 80% lower jig that makes it ridiculously easy for a non-machinist to finish their 80% lower in under 1 hour with no drill press required.
